Acu-Rite Companies Inc.
ENC 250™ SINGLE SECTION
Universal brackets are available from ACU-RITE for
mounting the reading head. SENC 150 & SENC 250
encoders use most of the same reading head brackets.
Custom designed brackets by the installer should be solid,
rigidly assembled components, attached to the machine with
[1/4-20] M6 fasteners minimum.
• Follow the procedure on page 7 to attach the reading head
to the bracket.
• Use allen wrench from set screw adjustment to slide
alignment brackets away from the reading head.
• Remove alignment brackets and save with this manual.
• Move the axis through its full travel. Confirm that the
assembly does not interfere with the machine movement.
• Return the machine axis to its center of travel.
• Align the center marks on the reading head and scale case by
sliding the reading head and brackets along the case.
• Locate and attach the reading head brackets to the machine.
• Align the bracket mounting holes with the reading head holes,
and secure brackets in place.
